That’s right no plastic. These strong picks are made of corn starch not plastic. They feel the same but are oh so Knot! The floss is bamboo coated with activated charcoal to help whiten your teeth. But we didn’t stop there. Infused in your floss is all-natural grape fruit seed extract (GSE) to deliver bacteria fighting properties directly to the bugs that cause gingivitis. Knotty picks will leave you feeling fresh with its minty flavor and these vegan picks will naturally biodegrade back into the earth. All goodness and nothing naughty in the Knotty Pick.
